In the present embodiment, the upper half body 4A and the lower half body 4B are divided into two parts, and the upper half body 4A and the lower half body 4B are combined into almost the same shape. It has a U-shaped horizontal space. Then, the winning ball cover 11 of the game board 3 faces the space area S surrounded by the mechanism board 4 in a U-shape. The lower half body 4B of the mechanism plate 4 has a winning ball collecting gutter 18 open upward, and receives all the winning balls discharged from the winning ball cover 11. The winning balls accepted here are sent to a winning ball processing device (not shown) in the lower half 4B and discharged to the outside of the machine.

The mechanism plate 4 is rotatably attached to a shaft by a hinge tool interposed between the mechanism plate 4 and the cross member 6. The mechanism plate 4 of this embodiment is divided into the upper half body 4A and the lower half body 4B as described above, and a hinge structure as shown in FIG. That is, the hinge tools A, B, C
Is a fixing member 19 fixed to the crosspiece member 6 of the front frame 2 with a screw.
A, 19B, 19C and rotating metal fittings 20A, 20B-1, 20B-2, 20C which are screwed to the mechanism plate 4 side are rotatably coupled to each other. Each fixing metal fitting 19A, 19
B and 19C are a mounting board 21 fixed to the side surface of the beam member 6 with a screw, and a horizontal arm plate 22 protruding from the mounting board 21.
The horizontal arm plate 22 is provided with a bearing hole 23 in the fixing fitting 19A, a shaft tube 24 protruding downward in the fixing fitting 19B, and an upward short shaft 25 in the fixing fitting 19C. There is.

The rotating metal fittings 20A and 20B-1 are the upper half 4A.
Further, the rotating metal fittings 20B-2 and 20C are attached to the lower half body 4B, respectively. Rotating metal fittings 20A, 20B-
1, 20B-2 and 20C are a mounting board 26 for screwing to the mechanism plate 4, an arm rod 27 vertically projecting from the mounting board 26, and a bearing plate 28 formed at the tip of the arm rod 27. And consists of. The rotating shafts 29, 29 are projected downward from the bearing plate 28 of the rotating metal fittings 20A, 20B-1 of the upper half body 4A.
Is loosely fitted in the bearing hole 23 of the fixing metal fitting 19A and the cylindrical hole of the shaft cylinder 24 of the fixing metal fitting 19B. On the other hand, a rotating shaft hole 30 is formed in the bearing plate 28 of the rotating metal fittings 20B-2, 20C of the lower half body 4B, and the rotating shaft hole 30 is fixed to the shaft cylinder 24 of the fixing metal fitting 19B. The short shaft 25 of the metal fitting 19C is loosely fitted. In addition, the shaft tube 24 of the fixing metal fitting 19B is the fixing metal fitting 19B.
It is formed to be slightly longer than the short axis 25 of C. Therefore, first, the rotating metal fitting 20B-2 is fitted to the shaft cylinder 24, the lower half body 4B is lifted until the bearing plate 28 is attached to the root portion of the shaft cylinder 24, and in that state, the rotating metal fitting is placed on the axis of the short shaft 25. 20C
If the lower half body 4B is lowered by aligning the rotating shaft holes 30 of the above, the rotating metal fittings 20B-2 and 20C are engaged with the shaft cylinder 24 and the short shaft 25, respectively, and cannot be disengaged.

By adopting the above hinge structure, the mechanism plate 4 can rotate the upper half body 4A and the lower half body 4B independently of each other. In addition, the rotating metal fitting 2 of the upper half 4A
By adopting the configuration in which one fixing metal fitting 19B is shared by the rotating metal fittings 20B-2 of 0B-1 and the lower half body 4B, it is possible to improve the efficiency of the fixing metal fitting work and reduce the burden of the component cost. Besides, reference numeral 31 in the drawing is a fastener for locking the mechanism plate 4 in the closed position.

Thus, the interference avoiding means of the first embodiment adopted between the mechanism plate 4 and the outer frame 1 has the structure of the hinge tools A, B and C. That is, in the conventional hinge tool 104, as shown in FIG. 7, the center of rotation of the mechanism plate 105 is set inside the rear edge of the outer frame 101, so that the mechanism plate 105 is rotated with the front frame 102 closed. When trying to do so, the outer frame 101 and the mechanism plate 105 immediately interfere with each other. Therefore, as shown in FIGS. 1 and 4, the fixing brackets 19A, 19B, 19

Can be rotated to a workable opening angle. Of course, the mechanism plate 4 (upper half body 4A, lower half body 4B) can be removed from the crosspiece member 6 by rotating it to this position.

[0015]

[Embodiment 2] FIG. 6 is a sectional plan view of a main portion of a pachinko machine showing Embodiment 2. The interference avoiding means of the second embodiment is in the structure of the outer frame 1. That is, the recess 32 for avoiding interference is formed in the outer frame 1 without changing the rotation center of the mechanism plate 4 from the conventional position. By doing so, the rotation-side end of the mechanism plate 4 and the outer frame 1 do not interfere with each other as shown by the two-dot chain line in FIG. 6, so that the mechanism plate 4 can be rotated even when the front frame 2 is closed. In order to clarify the recessed portion 32, FIG.
One form of the recessed portion 32 is indicated by a two-dot chain line for reference on the outer frame 1.

Although the present invention has been described with reference to the first and second embodiments, the present invention is of course not limited to the above embodiments. For example, the following items can be considered as specific examples of other variations. Although the mechanism plate 4 of the first embodiment is shown as being divided into an upper half body 4A and a lower half body 4B, the mechanism plate may be divided into three, or a mechanism plate having a general one-piece structure may be used. Can also be applied. In addition to the structure shown in the first embodiment, the structure of the hinge tool includes, for example, a short shaft and a long shaft projecting from the upper and lower surfaces of the bearing plate 28 of the fixing bracket 19B, and the rotating brackets 20A and 20B of the upper half body 4A.
The same rotation shaft hole as the rotation fittings 20B-2, 20C of the lower half body 4B may be formed in -1. Further, two fixing fittings 19B are provided to separate them for the upper half 4A and the lower half 4B, and bearing holes are formed in the bearing plates 28 of all the fixing fittings.
Furthermore, the same rotating shaft as the rotating metal fittings 20A, 20B-1 of the upper half body 4A may be projectingly provided on the rotating metal fittings 20B-2, 20C of the lower half body 4B. In the present invention, since the mechanism plate 4 can be rotated with the front frame 2 closed, the mechanism plate 2 is necessarily the game plate 3
The front frame 2 can be closed without superimposing on the back surface of the. Therefore, while carelessly forgetting to close the mechanism plate 4, the front frame 2
There is a risk that the mechanism plate 4 will rotate naturally during play due to the closing of the door or the locking failure. Therefore, it is conceivable to add a sensor for detecting that the mechanism plate 4 is in the closed position to the present invention. That is, sensors such as microswitches and reed switches are installed at points indicated by symbols X and Y in FIG. 3, and the fact that the mechanism plate 4 is in the closed position is sent to the control device by an electrical signal, and the mechanism plate 4 is When it is not in the closed position, the game is interrupted as the operating environment is bad, or it is set so as to notify the manager side. When a micro switch is used as a sensor, the switch body is fixed to the back surface of the mechanism plate 4, and the actuator piece is brought into contact with the back surface of the game board 3 or the back surface of the crosspiece member 6. When a reed switch is used as the sensor, the reed switch may be fixed to the back surface of the mechanism plate 4 and a small permanent magnet may be attached to the back surface of the game board 3 or the back surface of the beam member 6. By adopting such a configuration, it is possible to prevent problems such as forgetting to close the mechanism plate 4 due to carelessness and natural rotation of the mechanism plate 4 due to a locking failure as described above. Needless to say, the mechanism plate 4 in this case may have a single-piece structure or a multi-divided structure. However, in the case of a multi-divided structure, it is desirable to detect the closed position for each of the divided parts.

[0017]

As described above, in the pachinko machine of the present invention, since the mechanism plate and the outer frame do not interfere with each other because the mechanism for avoiding interference is provided, the mechanism plate can be rotated to an open angle that allows work even when the front frame is closed. Can be moved. Therefore, even if you do not open the front frame one by one, you can directly open the mechanism board from the back side of the outer frame, and freely open the mechanism board immediately after the completion of the pachinko machine until it is installed on the pachinko machine installation island. Inspection and adjustment work can be performed.
